SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 747,618, dated December 22, 1903.

Application filed August 26, 1903. Serial No. 170,867- (No model.)

To all whom it ntay concern:

Be it known that I, ADOLPH F. W. LORIE, a subject of the King of Great Britain, residing at Dunedin, New Zealand, have invented cer- 5 tain new and useful Improvements in Sashto ters Patent in the United States, filed July 2,

1902, Serial No. 114,130. The fastener as disclosed in said application comprises, among its main elements, a nut to be secured to the upper rail of the lower sash, a screw working I :5 through the said nut, and a plate secured to the upper sash,against which the screw bears for holding the sash in locked position.

The present invention consists in the features and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side View of the invention, and Fig. 2 is a front View with the handle raised. Fig. 3 is a plan View partly in' section, and Fig. 4 a

cross-section, of the nut. a detail.

In the drawings, 1 indicates the nut,which is secured to the top of the lower sash.

Fig. 5 is a view of 0 Through this nut a screw-rod 2 extends which is adapted to bear with its end against a strip 4, securedto the said rail of the upper sash, the said plate or strip having corrugations with which the end of the screw engages to At its inner end the screw is bent substantially at right angles in order toform a crank or handle portion by which the screw may be turned and set in looking or in unlocking position.

I provide a stop at the end of the screw which when the screw is retracted into unlocking position will arrest the movement of the screw by coming in contact with the nut. This stop is shown at 3,and consists of an unthreaded part at the end of the screw, preferthat whenthe screw is retracted to its utmostlimit and is unlocked the bent end of the screw forming the handle will stand in an inclined position upwardly and with its end plumb over the outside edge of the flange on the left side of the me, and it will be seen that a maximum movement may be obtained by the handle passing from this position to its lowermost position, in which the screw is fully advanced to engage the strip. Further, the stop as thus arranged'in relation to the nut insures proper adjustment of the parts, even in the hands of a careless person when affixing them, because this stop determines the position of the handle when the screw is fully retracted.

The swiveled stop is of advantage, further, in that it presents different parts of its wearing-face for contact with the corrugated strip.

The not is composed of two members 5 and 6,which are threaded to receive the screw and are provided with openings through which screws 7 pass and extend into the upper rail of the lower sash to hold the nut thereto. The nut is of special construction to compensate for wear, for which purpose the flanges 8 8 are normally separated from each other on one edge at 9, said separation extending to the opposite side ofthe screw-r'od,where the two flanges are'in contact at 10, being held at this point by a screw 11, which passes only through the two members of the out, but not into the wood. The separated flanges are held adjustably by a screw 12, by turning which the top memberof the nut may be set toward or from the lower member to get the desired contact or pressure on the screw-rod. This adjusting-screw 12, like the screw 11 above mentioned, passes only through the two metal members and not into the wood.

Referring to the plan view Fig. 3, it will be seen that the upper and lower flanges on the left side of the nut are shorter than those on the right side of said nut. This is important, as it is necessary to provide for the side play of the sashes, and by shortening the flanges on the side of the nut nearest the window-frame a space is provided to clear the parting-bead a. This allows the nut to be placed close enough to the frame to insure engagement of the screw-fastening bolt with the corrugated strip on the vertical rail of the upper sash in all side movements of the two sashes.

In order to lock the screw in its holding or looking position, I provide a lock in combination with the crank or handle, said lock comprising a rod 14,extending through an opening 15 in the handle or crank, the said opening being preferably inclined, so that when the crank is in its lowest position the locking rod or bar will extend downwardly at an inclination to the crank or handle and inwardly toward'the sash. The inner end of the looking bar or rod is bent downwardly and when in locking position engages a locking clip or plate 16, secured to the front face of the side rail of the lower sash. The locking bar or rod is provided on its upper end with a head 17, adapted to rest upon a shoulder 18, formed on the crank or handle and to rest in a recess 19 in the side of said crank or handle. The head is of such a shape as to present practically a flush exterior to the handle when the locking-bar is in itslowest position and the head is in the recess, excepting that the said head projects slightly at the lower points 13 to be grasped by the fingers. The crank or handle is also recessed on its inner side at 20 to receive the bent end 21 of the locking-bar, so that when the bar is raised a substantially flush inner surface will be presented along the crank orhandle to be grasped by the hand. In the operation of the device when the handle is turned down to set the screw in looking position the screw may be locked by allowing the locking-bar to fall into engagement with the locking-clip on the window, and in order to unlock it is simply necessary to raise the locking-bar and turn the crank or handle into its uppermost position.

The locking-clip 16 on the lower sash I form of sections 22, superimposed and held by screws 23. By this form of clip itmay be built out to the height desired from the sash to suit the position in which the fastener is attached to the upper rail.

In applying the fastener to windows diflicult-y has been experienced in the slipping of the nut from the position in which it was placed while the workman is placing or driving the screws into the wood, and I have therefore provided a plurality of spurs 24 on the bottom of the not adapted to enter the wood of the sash-rail. I preferably use four of these spurs on the nut, and after the nut is placed in the desired position it is simply necessary for the workman to tap the nut, which will cause the spurs to embed themselves in the wood, and thus hold the nut while the screws are being inserted and driven.

I claim as my invention 1. In combination in a sash-fastener, a screw rod, a nut through which said rod passes to engage a part of the window, said nut being formed of two members a screw passing through the two members only, for adjusting the contact with the screw-rod, and screws passing through both members and into the wood to secure the nut in place substantially as described.

2. In combination in a sash-fastener, a nut, a screw working through the same and having a bent end or handle and a lock for holding the screw against turning, substantially as described.

3. In combination in a sash-fastener a nut, a screw working through the same having a bent end or handle and a lock carried by the said bent end or handle when thrust forward to fasten the sash, substantially as described.

4. In combination with a sash-fastener a nut, a screw working through the same to engage a part of the window and havinga bent end or handle and a gravity-lock carried by the said handle, substantially as described.

5. In combination in a sash-fastener a nut, a screw working through the same to engage a part of the window and having a bent end or handle and a lock carried by the said bent end or handle and consisting of a rod or bar extending at an inclination and movably through the said handle, said bar being adapted to engage'a suitable projection on a part of the window, substantially as described.

6. In combination in a sash-fastener a nut, a screw working through the same and having a bent end or handle and a lock consisting of a bar extending at an inclination and movably through the handle, said bar having a head on one end and its other end bent and adapted to engage a suitable projection on a part of the window, substantially as described. I

7. In combination in a sash-fastener a nut, a screw working through the same and having a bent end with recesses upon its outer and inner sides and a locking-bar extending at an inclination through the said bent end or handle and having portions to fit the said recesses, substantially as described.

8. In combination in a sash-fastener, a nut, a screw-rod working through the same and having a bent end, a lock carried by said bent end and a clip to engage the lock composed of the superimposed pieces with means to hold them in place.

In testimony whereof I affix my signature in presence of two witnesses.

ADOLPH F. W. LORIE.
